4 Claims.

v This invention relates to new and useful improvements in a detach-able mattress support and has specific reference to a revision of the device shown in my Patent No. 2,067,515.

. The invention proposes to characterize the detachable mattress support by the fact that it has ahollow longitudinal member for extending acrossgthe end'of a mattress support which includes a frame and springs extending across the sides thereof. It is proposed to make the hollow longitudinal member with an open bottom and an open side for providing room for the passage of said springs.

Still further the invention contemplates the provision of cleats mounted on the bottom of the longitudinal member for engaging the end of the frame for holding the mattress attachment in place.

Furthermore, the invention proposes an arrangement for removably and foldably holding the upright support member of the attachment.

As another object of this invention it is pro-- posed to provide means for engaging against the frame to assist the cleats in holding the attachment in place.

For further comprehension of the invention, and of the objects and advantages thereoireference will be had to the following description and accompanying drawing, and to the appended claims in, which the various novel features of the invention are more particularly set forth. In the accompanying drawing forming a material part of this disclosure:

/ Fig. l'is a fragmentary perspective view of a detachable mattress support constructed QLCCQIde ing to this invention.

Fig. 2 is a fragmentary sectional View taken on the line 2-2 of Fig. 1. I

Fig. 3 is a fragmentary sectional view taken on the line 33 of Fig. 1. v

The detachable mattress support, according to this invention, is intended for use in conjunction with invalid beds and the like. It is intended to prevent the mattress upon such a bed from slipping when a portion thereof is in the inclined position. In Fig. 1 a portion of an invalid bed is shown which includes a mattress support Ill having a hingedly connected end portion Illa which is adapted to be raised and lowered as cone ditions warrant. The mattress support In is of frame-like form and is formed on the inner sides with a plurality of openings I I. Between the opposite sides of the frame of the mattress support a plurality of springs and supporting wires I2 are secured through said openings I I. These wires form a spring structure for supporting the mattress.

The detachable mattress support includes a hollow longitudinal member I4 for extending across one end of the mattress support Ita An *5 upright support member I5 is mounted on the said longitudinal member I4 for engaging the end of a mattress resting on said mattress support. The bottom and one side of said longitudinal member I4 is open for providing room for {[0 the springs I2. I

The longitudinal member I4 is formedfrom a strip of sheet material which has its ends Ila and one side Mb bent downwards to form' the hol- 7 low construction, Consequently, the bottom and '16 the opposed side is open. This hollow longitudinal member is of a size so as to be capable of being seated over the spring structure I2 at the end of the mattress support.

The upright support member I5 comprises a go bottom tubular element I6, a top tubular element I I, and a plurality of connecting elements I8. The end connectin elements, indicated by the numerals I8, have extended bottom end portions I8a which abutagainst the top face of the longitudinal member I4 to hold the upright .support member in an upright position, as more fully explained hereafter. The bottom tubular member I6 is removably and turnably supported ;on I the longitudinal member l4 so that the upright 0 support member I5 is foldable downwards as indicated by the dot and dash lines I5 in Fig. 2.

At the ends of the longitudinal member I4 there are vertical lugs 20. A stem 2| engages through each lug 20. The outer ends ofthese stems have heads 22 by which they may be manipulated. The inner ends 2Ia of these stems -2I are adapted to engage into the open ends ofthe bottom tube IS. A cam element 23 is fixedly mounted intermediate the ends of each of .the stems 2|. A spring 24 is coaxially mounted on each stem 2| and acts between the lug 20 and the element 23 for resiliently urging the stem inwards to engage the tubular member I6. Normally, the stems 2| support the upright support member I5 so as to be foldable as indicated in Fig. 2.

- Cleats 25 of hook shape are mounted upon the bottom face of the longitudinal member I4 and are cooperative with the end of the frame of the mattress support II] for holding the attachment in position. To assist these cleats the cam elements 23 are engageable through slots 26 (see Fig. 1) in the top of the longitudinal member I 4 to extend downwards and abut the mattress support I!) as clearly shown in Fig. 2. The cam elements 23 provide suflicient upward stresses to hold the hook cleats 25 firmly in their holding positions.

When it is desired to remove the attachment, the heads 22 may be turned through approximately 90 so as to extend upwards the cam elements 23, up through the slots 26. The attachment is now free and may be moved to disengage the cleats 25. Furthermore, the heads 22 of the stems 2| may be drawn outwards to disengage the inner ends 2 la from the bottom tubular member l6, and then the upright member 15 is removable.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit or the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is: I

1. A removable attachment for invalid beds and the like, adapted to prevent the mattress from slipping when in an inclined position, comprising a hollow longitudinal member for extending across the end of a mattress support which includes a frame and springs extending across the sides thereof, an upright support member with a horizontal bottom tubular portion for the end of a mattress resting on said mattress support, and the bottom and one side of said longitudinal member being open for providing room for said springs, cleats secured on the bottom of said strip and adapted to engage the end of said frame for holding the attachment in place lugs mounted on said longitudinal member slightly spaced from the ends of said horizontal bottom tubular portion, stems slidably mounted through said lugs and engaging into the ends of said tubular portion for turnably and foldably supporting said upright member, cam elements on said stems adjacent the ends of said horizontal tubular portions and engaging slots in said hollow longitudinal member, and resilient expansion means acting between said cam elements and said lugs.

2. A removab-ly attachment for invalid beds and the like, adapted to prevent the mattress from slipping when in an inclined position, comprising a hollow longitudinal member for extending across the end of a mattress support which includes a frame and springs extending across the sides thereof, an upright support member with a horizontal bottom tubular portion for the end of a mattress resting on said mattress support, and the bottom and one side of said longitudinal member being open for providing room I therefore reserve the right and for said springs, cleats secured on the bottom of said strip and adapted to engage the end of said frame for holding the attachment in place, lugs mounted on said longitudinal member slightly spaced from the ends of said horizontal bottom tubular portion, stems slida-bly mounted through said lugs and engaging into the ends of said tubular portion for turnably and foldably supporting said upright member, cam elements onsaid stems adjacent the ends of said horizontal tubular portions and engaging slots in said hollow longitudinal member, and resilient expansion springs coaxially on said stems and acting between said cam elements and said lugs.
